The Konica Autoreflex T4 (1976) is the successor to the well-regarded Autoreflex T3 (1973) and the final body in Konica's flagship Autoreflex T series. It retains the AR bayonet mount and the shutter-priority automatic exposure mode that defined the T line, while updating the metering cell to a silicon SPR type for faster response and improved low-light sensitivity compared to the T3's CdS-based system. The shutter is a horizontal-travel Copal Square metal blade unit running 4s to 1/1000s, with a mechanical fallback at ~1/60s if batteries fail. Like the T3, it accepts the full range of Konica Hexanon AR lenses. The T4 arrived at an unfortunate moment: Canon launched the AE-1 in 1976 with aggressive marketing and a lower price point, and the T4 never achieved the commercial traction Konica needed.

The Autoreflex T line began with the original Autoreflex T in 1968 — one of the first Japanese SLRs with TTL metering. The T2 (1972) and T3 (1973) refined the system. The T4 (1976) was the terminal model in the T sequence; Konica then pivoted to the consumer-oriented TC and TC-X bodies before the FS-1 (1979) introduced the integrated motor drive. The Autoreflex T4 was discontinued around 1979.
Konica's AR system was ultimately a dead end commercially: Konica never delivered autofocus in the AR mount, while Canon EOS and Minolta Maxxum redefined the market in 1985-1987. Konica exited 35mm SLRs in the early 1990s.
The T4 is the final chapter of Konica's most capable manual-focus SLR line. Its significance is primarily as the culmination of the Autoreflex T development arc — the T3 is more collected and better known, making the T4 a somewhat overlooked conclusion to the series. For AR-mount users, the T4 offers the most refined body in the line with the silicon metering upgrade.
For 2026 buyers, the T4 is a modestly priced entry into the Konica AR system at $80-220 used. The AR lens ecosystem — particularly the Hexanon 50/1.4 AR, 40/1.8 AR, and 135/3.2 AR — is undervalued relative to equivalent Canon FD and Nikon AI glass.
Konica AR bayonet mount. Fully compatible with all Hexanon AR lenses produced from 1965 onward. Notable glass for the system:
Motor winder: The Auto Winder AE was produced for the TC/TC-X but compatibility with the T4 should be verified.
